I do my lessons on zoom on weekday evenings and a time suitable to both of us on weekends.
Through the course, after teaching I will put questions and set homework to consolidate if I sense the topic is not fully understood. I also do multiple exam style questions with my students to make sure that they learn exam technique.
As mock exams and the actual GCSE approach , the length of lessons would be lengthened and we can do a mock exam im person or online which would be marked and graded. Learning is all about progress so I do tend to make progress trackers for students for the journey into grade 8/9s
